The building in question is The Centre (中環中心) and isn't that far away from the IFC in all honesty - just a few hundred yards at most.

Batman: The Dark Knight - Christian Bale (2008) - The Centre, Central
Even though it is the International Finance Centre tower (that's the smaller one of the two) that we know is the HQ of the Chinese criminal (played by Chin Han) and the one that Batman crashes through the window to capture him, it was another building that served as the lobby for the earlier scenes when Morgan Freeman plants the cellphone in the security desk. It was also this other building that we see a police van head towards as the police arrive on the scene to deal with The Batman.
